You want to crawl millions of URL and make a super SEO Audit ?
Here are the best crawler for SEO on a large to very large website:
- Desktop SEO Crawler (starts at more or less 200$ / year / unlimited crawl)
- Screaming Frog (Linux / Windows / Mac OS) -> The big plus: native function to cross data from G.A., Search Console, MajesticSEO, Ahrefs… + You can cross with your log files ! +/- 60 GB of disk space for 1 million URL crawled. Read this post to setup Screaming Frog on Remote Desktop Ubuntu Cloud instance.
- Sitebulb (Windows / Mac OS) -> pretty rich ! Interesting visualization of the internal links structure.
- Hextrakt (Windows) -> URL Segmentation is a real + when it comes to analyze Big Websites. Hextrakt does the job !
- Xenu (Windows) -> only for very basic checkup, like 404.
- SaaS SEO Crawler (starts at +159$ / month / for 2 millions URLs crawled per month)
- Kelogs (Im the founder, and we have the best price ;))
- Botify
- OnCrawl
- DeepCrawl
- FandangoSEO
- Open Source SEO Crawler (Python / Java etc. )
- Scrapy
- Crowl (An Open Source crawler based on Scrapy)
- Nutch
- => Those solutions aren’t profitable in most cases, since it requires a lot of development and maintenance compared to a SaaS solution for instance.
- => Nevertheless, if you want to discover how a search engine works, you will learn a lot ! 🙂
